Do not fail probing when device_init_wakeup fails.
device_init_wakeup fails when the device is already enabled as wakeup
device. Hence, the driver fails to probe the device if:
- The device has already been enabled for wakeup (by e.g. sysfs)
- The driver has been unloaded and is being loaded again.
This goal of the patch is to fix the above cases.
Overwhelming majority of the drivers do not check device_init_wakeup
return code.

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

gpiod_get_value() can return negative values if an error occurs.
In several places this error code was ignored.
Ensure that errors codes are handled correctly throughout the CEC
pin framework and CEC pin drivers.
The return code of the cec_pin_ops read() callback had to be changed
from 'bool' to 'int', which mean the prototype of that callback in the
sun4i drm driver also had to be changed.

While select would be a great idea for most archs, this
causes a breakage with s390:
"I don't think that's a good idea, as it suddenly enables selecting all PCI
drivers on platforms that do not have PCI.
WARNING: unmet direct dependencies detected for PCI
Depends on [n]: HAVE_PCI [=n]
Selected by [m]:
- CEC_SECO [=m] && MEDIA_CEC_SUPPORT [=y] && (X86 || IA64 || COMPILE_TEST [=y])

Most CEC platform drivers are using VIDEO_*_CEC pattern, some with
an _HDMI extension too.
Well, they're not related to V4L2 support, and we don't really
need those big config names. So drop VIDEO_* from them, remove
_HDMI (if present) and move CEC to the start.
This way, all platform driver options are now CEC_<driver>.

As CEC support doesn't depend on MEDIA_SUPPORT, let's
place the platform drivers outside the media menu.
As a side effect, instead of depends on PCI, seco driver
can select it (and DMI).
